Written communication. Writing concise, direct, accurate, and easy to read emails/jiras/etc. If you're a dev or not this holds true. Your boss and your bosses boss are busy. Help them understand what you do by writing your thoughts clearly. The other is finishing. Work on things you can finish. Don't aim to rebuild Rome in an afternoon.
